Heavy metals complexes of poly(sodium 4-styrenesulfonate) — thermogravimetric studies

(in English)

Polimery 2012, No 4, 290


DOI: dx.doi.org/10.14314/polimery.2012.290

Summary

The paper analyzes thermal properties of poly(sodium 4-styrenesulfonate) bound with different metal ions [Cu(II), Ni(II), Zn(II), Pb(II), Cr(III)] and in the acidic form. Solid samples of polyelectrolyte bound with different counter-ions were prepared and their mass losses in the temperature range of 25—1000 °C were recorded. TG and DTG curves were used to estimate the activation energy of thermal degradation of sulfonic groups bound with different counter-ions. For studied polyelectrolyte counter-ions, the sulfonic group thermal stability increases in the following sequence: H << Ni << Cu << Na << Zn << Pb << Cr(III).


Key words: polyelectrolyte, heavy metal complexes, thermogravimetry
